Abstract. CCD is important in many fields, but Geodesy uses it mainly for Laser tracking. An ideal
supplement is Astrogeodesy, e.g. with our mobile zenith camera ZC-G1. It was developed 2001-02 for
semiautomatic astropoints of alpine surveys or difficult technical projects. In the next years we'll improve
parts of the Austrian geoid by 50% to ±1-2cm.
Astro control of polygons and networks raises accuracy and economy remarkably: 2 sun azimuths of
±3" increase both by ∼40%! The additional effort is only 10-20%; 5min sunshine should do. We plan
to use servotheodolites and invite interest groups to cooperate.
